Traffic had to be re-routed around the two blocked northbound lanes of Mountainview Rd. South in Georgetown in front of St. Andrew’s United Church late Wednesday morning after a car struck a tree. A person was extricated from the vehicle just before noon after it left the roadway and hit a tree on the boulevard. A Halton Regional Police spokesman said the victim suffered a broken leg but wasn’t able to provide any additional information. The driver of a tractor-trailer driving northbound on Mountainview was questioned by officers on the scene.
